# 1.13.6

> Build environment: NodeJS `18.16.1`, NPM `9.8.0`

Changes:

Changes:

* Programmatic hyperlinks (InDesign style): "will-navigate" event intercept now works where no-HTTP streamer is used (in which case there is no HTML base transform)
* Fixed-layout workaround: CSS 2D transform (scale + translate) bleeds body background color, this is prevented using a transparent image on HTML root element
* Check that webview is still mounted after the async timeout (show/hide content mask IPC event)

Changes:
* Fixed TTS readaloud issues: paginated doc with odd number of columns, last page of spread is left-aligned, but TTS playback and highlight was unshifting the page spread. Also fixed: when large sections of text are single HTML element => scroll-into-view did not show current sentence / work highlight.

TTS utterances can be clicked to start playback (hit testing based on fragmented strings of characters / DOM ranges).
* TTS readaloud simplified "overlay" view is now opt-in, default is in-document highlighting.

* TTS readaloud: improved presentation styles for sepia, night and normal modes.
* TTS readaloud: new features, emphasis on heading levels, and inline display of images with "alt" attribute.
* Annotations / highlights: vastly improved rendering performance (DocumentFragment to build DOM, then batch-append highlights "layer" into actual document, also better mouse interaction / hover detection).
* Annotation / highlights: display improvement, using "mix blend mode" with opacity, yield better text legibility.
* Annotation / highlights: SVG and HTML renderers now default to "background" drawing style, with "underline" / "strikethrough" optional choices (was hard-coded before, now in API).

* Fixed Media Overlays night and sepia highlights
* Fixed SVG xlink:href relative URL handling
* Disabled FXL scroll during element focusing (mouse, keyboard interactions)
* Workaround for fixed layout documents that do not size the body correctly (force width + height dimensions)
* Visibility mask improved for fixed layout documents (smooth fade effect)

# 1.1.52

> Build environment: NodeJS `12.16.1`, NPM `6.14.4`

Changes:
* NPM updates (minor)
* workaround for application/xhtml+xml not handled correctly in xmldom lib
* support for audio/video autoplay (Electron command line switch)
* support for audio background looping track (epub:type = ibooks:soundtrack)
* in order to bypass Electron registerStreamProtocol() bugs: instead of static DOM patching of audio and video src URLs (replacement of custom URL protocol/scheme with direct HTTP streamer address), we now inject `<base href="HTTP_URL"/>` (this benefits all resolved absolute URLs, including scripted ones from mutated dynamic DOM, and does not affect the sandboxing of localStorage, IndexedDB etc. which is afforded by the custom URL protocol/scheme)
* fixed handling of iframes inside publication HTML documents (forwarding of query params, and allows same-origin scripting by bypassing the aforementioned `<base href="HTTP_URL"/>` of the host document, recursively)
